RC电路时间常数的一种增大方法

A method of how to increase the time constant in RC circuit

给出一种RC电路时间常数的增大方法 ,该方法基于晶体三极管基极和集电极电流之间的关系iC=βiB,可获得用小电阻。

This paper gives a method of how to increase the time constant in RC circuit. This method is based on the current relation i C=βi B between the base and the collection of triod transistor. Thus, the big time constant can be obtained by small resistance value and capacitance.
